To all 107mm it may concern.'

Be it known that l, linu'rs A. Konin a citizen ot the llnit'ed ltates.resid' 113; at l?hiladelphia in the county ot Philadelphia and State oilennsylrania, have invented new and usetul improvements in tier-eenFrames: of which the following is a specification.

This invention relaties to metal screens and frames theretor and it hasmore particular reterenee to that type ot trame for containing a screenof the usual diamond shape mesh to be applied to doors, Windows, orother similar openings. The primary object ot my invention is to providea trame of the foregoing type composed oit separate parts or memberswhich when the screen is inserted in proper relation thereto may beinseparably brought together and to the screen thereby forming` acomplet@ strong', and unitary screen and trame structure that cannot bereadily diszssemloled.

"With the foregoing and other objects in view this invention'oonsistsessentially in the novel features ot Construction7 combination andarrangement oit parts hereinatter 'Fully described and more specificallydetined by the appended claims.

ln the Jfurther disclosure et the invention reference is to be had tothe aecompauyine; sheet of explanatory drawings eonstitutii a part otthis specilioation and. in which like characters ot reierenee designatethe same or eorresmondinp` parts in all the views.

1Figure l is a 'liront elevation ol my deviee with the sereen and.'l'ralne assembleth a portion of the 'trame being-inkoken away andshowing' the relation of the iframe to the screen.

Figure 2 is a perspective view ot a portion o'f the auxiliary flange orlocking' member which co-operates with the main member.

Figure 3 is a perspective vieiv ot a portion ol the case or main tramemember and illustrating its peculiar formation; and,

Figure l is a cross sectional view taken approximately on the line 2 2in Figure l and showing' the relation of the parts as assembled with theclip stra-p or clamp member 'tor binding' the parts together.

lieten-ing .more particularly to the views the main trame memberis'designated by the numeral l and it is 'formed troni a blank of sheetmetal or other suitable material and it is bent when viewed in crosssection of appropriately the shape of the letter C with Serial No.559,850.

a flattened barok and an exaggerated extended base.

The secondary 'traine member is also termed troni a blank ol. sheetmetal or other suitable material and it is bent When viewed in erossseetion to appropriately the shape ot the letter l.. Y i

A third member 53 is also iliorinedftrom a blank ot Vsheet metal orother suitable inaterial-and it is bent when viewed in cross section toappropriately the shape or the letter ll. '.lhis member 3 issubstantially a clip strap or clamp member which is provided to bridgeover the extended adjacent edges ot the annular members l and 2 atspaced intervals or whenthe trame is assembled and lined thereto to holdthe parts `rigidly together and liorm a unitary strueture ot the tran'ieand screen.

The screen' 4 as shown in the drawing is a Wire screen o'l the diamondshape mesh or any other suitable soreen may be employed vwhich is ofsuch construction that .it may be held iin clamped relation With the`two trame portions l and 2 when the screen and'lramo are assembled.

The main trame member l, is n'iore particularly tornied with asubstantially vtlat side or Wall portion 5 and a lateii'ally extendedanggrularly disposed r'lann'e or lip G `which proieets'ti'oin one sideot said side or Wall' portion with said lip portion 6 in a planesubstantialli7 at rie-bt angles to the said Wall portion 5 From theopposite edge ot they base portion 5 there is 'formed another laterallyextended angrularly disposed longitudinal 'flange portion 7, the upperportion ot which extends toward the opposite tlange portions 6 and itlies in a plane substantially parallel to the plane of the side or Wallportion 5, thus making; the frame member l a more or less Channel-likeConfiguration.

The secondary frame member 2 is more particularly `formed with asubstantially tlat -base portion 8 and a, laterally extended an-,Qularly disposed longitudinal flange portion 9 projecting lrom one sidethereoiC substantially at right anggles to the aforesaid portion i rllhesecondary trame, member 2 is oil such dimensions and the base and flangeportions are so disposed in relation to each other that when the partsoi the trame are assembled in operative relation the upper face of thebase 8 of the frame member 2 will lie adjacent to and abut against theinner face of the flange portion 7 vof the main frame meinber l; and itwill be held firmly against said flange portion 7 while at the same timethe flange portion 9 of' the member 2 will entend laterally adj aeent tothe flange or li member 6 of the main Jframe member l in a planesubstantially parallel to :the plane of the flange member 6 by beingspaced slightly apa-rt from said flange member 6. rhe flange members 9and 6 are spaced apart to permit the insertion between them of thescreen el and as can be readily seen they are easj.' adjustable` towardor from each other so that screens of dillerent thickness can beaccommodated by my style of rame i' irinly held therebetween with equalrac 'lhe members l and 2 are made or cut in any suitable lengths toconform to the opening to be screened and the abutting ends of the outermain frame member l where they are needed to ybe joined as in the caseof the corner join-ts in the screen shown in Figure l they may berigidly connected by brazing or spot-welding or in any other manner thatwill ensure unitary structure o'l the main portion .of the screen frame.The main lframe members which having been assembled and rigidly joinedtogether as described yto malte the main portion of t-he frame asuitable screen l is inserted into said frame with a margin adjacent itsedges resting on and supported by a lip portion (i of the main framebody l. The secondary frame members 2 are then inserted into the framebody 1 taking a position above and engaging the marginal portions of thescreen and also engaging the main frame body l. The upper face of thebase 8 of Vthe secondary frame member 2 when in position will engage anddraw against the inner tace of the flange member 7 of the main framemember l, while the flange member 9 of the secondary frame member 2 willengage and rest against the marginal portions ot the screen l which isof course of such di inensions in reference to the main frame body as tosubstantially lill said frame body and provide suitable marginalportions for the secondary member to grip.

k'ilhe secondary trame member '2 being placed as described, I then bindthe sti-ruc- .ture of frame members l and 2 and screen l carried therebyinto fixed rigid relation making a practically unitary structure bymeans of theU-shaped clip straps or clamp members 8. These clip strapsor clamp inembers 3 bridge over the extended adjacent edges o'f` theflange members 6 and 9 of the main frame member 1 and secondary member 2and engage the opposite outer faces of these flange members `6 and 9,`the spaced points around `the length of said frame members therebydrawing the frame members l and r2 into firm gripping engagement withthe screen l in order to hold the parts in rigid relation. The clipstraps or clamp members 8 after being placed as d-eseribece are held intheir desired position to clamp the whole assembled device in one uniary `structure by being brazed7 spot-welded oi otherwise suitablysecured to the main and secondary frames.

From the foregoing description it will be apparent to those acquaintedwith the art that the main advantages of injidericc a .e its durabilityand strength due to its l t construction, also the ease et as' L theparts together, while it will screen any size or shape ot openings byadapting the frame member lengths to the dimensions of the opening to bescreened. Still further it is to be noted that while l have t escribedand shown the best form of my invention at present known to me the sameis susceptible of' minor detail changes and the right is herebyaccordingly reserved to make such changes and variations as fairly lievwithin the scope of the appended claims.

Having described my invention, what I claim as new and desire to secureby Letters Patent is:

l. 4ln a` screen 'frame the combination of a main frame member having across sectional base substantially corresponding to the letter C with anextended lower lip portion, a secondary substantially L-shaped framemember engaging inside the fla-nge at the inner portion of the mainframe, and binding or clamping means engaging the lip portion of saidmain frame member and main'body of the secondary frame member to bindsaid members in rigid operative relation as a unitary structure.

2. In a screen frame the combination of a main frame member having across sectional base substantially correspondingto the letter C with anextended lower lip portion, a seconda-ry substantially Lshaped framemember engaging` and interlocking portion of the main frame, and ascreen mounted on said main frame member and clamped in rigid relationthereto by and between said lip portion of said main frame member andthe main body of the interlocking secondary frame member.

3. In ascreen the combination of a main frame member having acrosssectional base substantially corresponding to the` letter =C with anextended lower lip portion, a secondary substantially L-shaped framemeinber engaging and interlocking with a flange portion of said mainframe, a screen mounted on said main frame lmember' between said :lipportion of said member and the interlocking secondary L-shaped framemember', and substantially U-shaped clamping means engaging the lipportion of said main iframe member and the main body of said secondaryframe member for ylocking said members and screen in rigid operativerelation es zi unitary structure.

4L. In a screen, n mziin frame oi? substantially C-shepe in crosssection and provided with in outer iip disposed substantially zit right:ingles to the body of the freine, n securing` member of substantiallyL-shape in cross section and having its base portion engag-ing inside ofthe flange at the inner portion or' the main frame and co-operatingtherewith to provide n ruler-um for the securing` member, av piece of'abrie having its edge portions secured between the iip or the meinframe and the mein body of the securing member, and means for securingsaid main body and the seid lip together.

5. In e screen, a main :trame of substantiziliy C-shape in cross sectionund provided with an outer iip disposed substantially et right ingles tothe body oit the frame, a securing member' of substantially L-shape Vincross section end having its brise portion engaging inside of the Hngeat the inner portion of the main frame and eo-opemting1 therewith toprovide a fuierum for the securing member, ay piece of fabric having itsedge portions secured between the lip ot the main frame and thel meinbody of the seeur ing member, :ind retaining lips secured about saidmain body and the lip for securing the same together.
